$PEGIFICATION forming part of Letters Patent N 0. 541,953, dated July 2,1895. Application filed November 17, 1893. Serial No. 491,273- (NOmodel.)

To all whom it may concern.-

Be it known that I, EUGENE H. TAYLOR, of Lynn, county of Essex, State ofMassachusetts, have invented an Improvement in Paper-Box-MakingMachines, of which the following description, in connection with theaccompanying drawings, is a specification, like letters and numerals onthe drawings representing like parts. I

This invention has for its object the production of a rapidly operatingmachine adjustable within very wide limits, for the manufacture of paperboxes and their covers, whereby the stock from which they are made,whether heavy or light, may be acted upon with equal facility, and thefinished article accurately and quickly produced.

In this machine, as will be hereinafter described, the blanks from whichthe boxes or covers are to be made are placed in'position betweenadjustable guides located above a tank containing wetting devices andpasting devices, the undermost blank of the pile of blanks beingsupported between its ends on suitable tracks, the wetting devicesrising at the proper time and wetting the said undermost blanktransversely and longitudinally in the lines on which it is to besubsequently folded, to form the flanges or sides of the box or cover,the width of the flanges depending on the depth of the box or cover tobe made, while the pasting devices rise and apply paste to parts of theblank to be-turned over, in order that other parts of the flanges may bepasted tothem, the wetting and pasting devices in their generalconstruction and -arrangement being substantially as shown and describedin United States Patent No. 418,690, granted to George H. Oushman andmyself January 7, 1890, particular features and differences thereoverbeing hereinafter particularly described and claimed. The blanks of thepile arethereafter fed forward one by one from the bottom of the pilebya feeder along supporting tracks into position between a former andafollower, both of which are suitably guided and made movable verticallywith relation to said tracks or to the bed of the machine, and the wetand pasted blank is carried up by the former to the follower, and caughtand held between them, and the projecting portions of the blank are thensubjected to the action of lip turners, which positively turn the sideand corner flaps of the blank over upon the former,-after which theformer rises with the blank, taking with it the follower, the former andfollower together moving the blank held between them past side and endplates or wipers, the latter causing the end flaps of the blank to bewiped or turned down upon the corner flaps,previ.ously turned over andheld upon the former by the lip turners.

As herein shown, the flanges or edges of the blankwhich are toconstitute the sides of the box or cover are first turned down by thelip 'turners, after which continued movement of the said turners foldsthem and turns the corner flaps snugly-about the corners of the former,the lip turners remaining stationary in such position' and holding theside and corner flaps against the sides and ends of the former,untilfurther vertical movement thereof causes the end flanges or flaps of theblank to be turned over upon the corner flaps. When the end flanges orflaps have been. thus turned down against the corner flaps the formerhas reached the limit of its upward movement, and it is arrested. Theblank is then subjected to compressing mechanism to complete the sidesand ends of the box or cover, after which the formerand follower and thelip turners return to their normal positions, and an ejector deliversthe completed box or cover from between the separated former andfollower.

In accordance therewith my invention consists in the combination, with aformer, of compound lip turners located at the corners thereof, andactuating means to automatically move said lip turners toward the sidesof the former, a portion of the lip turners being made to turn at rightangles to the other portion and about the corners of the former, wherebythe sides and the corner flaps of a blank are turned over upon the sidesand ends of the former, substantially as will be described; also, in thecombination, with a former, of compound lip turners located at thecorners thereof, adjusting devices for thelip turners, and actuatingmeans to automatically move said lip turners toward the sides of theformer, a portion of the lip turners being made to turn at right anglesto the other portion and about the corners of the former, whereby thesides and the corner fiaps of a blank are folding lip turners locatedadjacent the CO1.

ners thereof and normally extended in the same plane, and actuatingmeans to move said lip turners simultaneously toward the sides of theformer, to turn the side flanges of a blank, and thereafter toautomatically swing or fold portions of said lip turners around thecorners and ends of the former, to thereby turn the corner flaps of theblank inward against the ends of the former, substantially as will bedescribed.

Other features of this invention will be hereinafter described andpointed out in the claims at the end of this specification.

Fig. 23 isan upper side view of the follower. Fig. 2" is a section thereof on theline t y, with the plunger in position. Fig. 25 shows end and side viewsof the locking devices on the plunger, to be described. Fig. 26 is a topview of a completed box, the shape of the blank being shown in dottedlines. Fig. 27 is a plan view of the bed of the apparatus below thehead, with the side and filling plates in position; and Fig. 27 is adetail in perspective, to be described.

The side frames A, of suitable shape to support the operating parts ofthe apparatus, are rigidly secured to or form part of a base A and areconnected and support at their tops a bed-plate A, of suitable shapetosustain the feeding and positioning devices to be described.

The side frames and base are provided with suitable pedestals supportingbearings A A for a cam shaft A see Figs. 2, 4, 6 and 8, having thereon aseries of cams B, O, D, E, and F, shown separately in Figs. 16 to 20,inclusive, the cams B at the outer ends of the shaft being similar, andoppositely faced.

As best shown in Figs. 3 to 6 inclusive, an arm E preferably formed as atruss, is pivoted at E to the base of the machine, and a link Epivotally connected thereto at E is shaped to form a guide slot at itsfree end, as at E see Fig. 6, and shown in dotted lines Fig. 4, toembrace the cam shaft A, the said link having thereon a suitable rolleror other stud E see dotted linesFigs. 2, 4 and 6, to enter and beactuated by the cam surface E ous that any other suitable or desirableconstruction may be used.

The bed plate A is rearwardly extended, as shown, at the feed end of themachine, see Figs. 11 and 12, and undercut plates aare secured theretoto form longitudinal guides or ways for the frame G, see Figs. 5 and 11,and

shown separately in Fig. 12 to which is adjustably secured the feeder G,by suitable bolts 9, the said frame G being connected to the upper endof the arm E by a short link g, shown in section in Fig. 5 and in dottedlines in Figs. 3, 11 and 12, and thereby reciprocated horizontally backand forth in the guide ways a.

The frame G is best shown in Fig. 12 as skeleton in form to reduce itsWeight, and has longitudinal guide flanges G upon its upper side. i jThe adjusting bolts g are extended through longitudinal slots g of thefeeder, whereby the position of the forward end of the feeder isadjusted to the width of the blank M, see Fig. 26, to be acted upon,such adjustment being necessary to adapt the machine to various widthsof blanks, inasmuch as the throw of the frame G is constant.

The feeder is slotted centrally at G see Figs. 7 and l], to enable it topass the central track I), to be described, extending to within a shortdistance of the former, as best shown in section, Fig. 5.

The forward end of the feeder G is beveled as at 2, Figs. 5 and 7, toreadily pass under the blank, the said feeder, immediately back of itsbeveled. front end 2, having attached to it plates g most clearly shownin Fig. 5 the front edges of the said plates meeting one of the longsides of the blank, it being supposed that the feeder and blank, notshown, are moving in the direction of the arrow 200, Fig. 7, thecontacting edges of the said plates preventing the blank from slippingon the feeder while being fed. The plates g are attached to the feederby suitable screws 3, whereby they may be readily replaced when worn.

Side tracks I) are secured to the upper portion of each paste pan H,parallel to the central track 17, said tracks serving to support theblank, to be fed forward by the feeder, between the points where thesaid blank is wet and where. it is pasted, or just outside the line onwhich the blank will be folded to con stitute the ends of the box orcover.

The blanks M of paper-board, all properly notched, as in dotted linesFig. 26, to form end and corner flaps and side flanges, are placedin apile between suitable guides K,- herein shown as plates,-having at theiroppositeends internally threaded bearings 7.0, is, respectively, toreceive therein the rightand lefthand screw threaded adjusting guiderodsK, K the said guide rods being supported respectively in suitable standserected upon the bed plate A, and in brackets k secured to the head ofthe machine. Like bevel gears k are secured to the rods K, K best shownin Fig. 7, to engage gears k and k on a connecting shaft 70, suitablysupported in hearings on the bed plate A, and as herein shown one end ofthe rod K is shaped to receive a crank arm see Fig. 1,

whereby it maybe rotated, such rotation, by'

means of the described bevel gears and connecting shaft 7c, alsorotating the rod K to simultaneously move the guides K toward or fromeach other in parallelism, to rapidly and accurately adjust them to thelength of the blank.

The guides are horizontally slotted, as at 70 see Figs. 3 and 5, toreceive therethrough the shank of an adjusting screw 70, secured to ablock 70 provided with a fin 70 shown only in Fig. 7, to enter and beguided by the re: cess k at the inner side of the guide K, see Fig. 5,the said block having pivoted thereto a gage carrier 7e extendedlaterally from the inner side of the guide, as best shown in Figs. 7 and7 and to. which carrier is rigidlysecured a slotted finger 70surrounding a threaded post 70 A spring 3 surrounds the said postbetween its head and the finger 70 as clearly shown in Fig. 7 and aninternally threaded collar or nutir, engages the threaded portion of thepost between the block km and the finger 2514.

The gage carrierk is slotted longitudinallyto receive the shank of a setscrew 5 attached to the vertical gage it", see Figs. 1 and 7 the saidgages 7c" determining the position to be occupied by the rearmost sideof the blank or pile of blanks nearest the feeding end of the machine.

The main adjustment is made by means of the set screws k by which theblocks 10 may be moved bodily along the guides K and secured in place,and the vertical gages 10 7 may be adjusted toward or from the center ofthe machine on the carriers 70 by the set screws 5, according to thelength of the blanks. ter the blocks have been adjusted to theirapproximate position, a finer adjustment may be given to the carriers byturning the nut or collar 70 on the threaded post 70 such movementturning the gage carrier 70 on its pivot and enabling a very fineadjustment of the vertical gages to be made.

It sometimes happens, when the blanksare cut from thin or light stock,that the ends thereof beyond the wetted portions, after re ceiving thepaste, will bend or fall below the level of the tracks 1), b, or out ofa horizontal plane, resulting in an improper presentation of the blankto the former, and to obviate this bending and always present theblankin a horizontal plane, I have provided adjustable auxiliary tracks6 beyond the said tracks 17', as best shown in Fig. 7.

The base of each guide K is slotted, as at U, shown in dotted lines,Fig. 3, and in full lines at one side of Fig. 7, one.of the guides Ktherein being shown as broken away, to receive therein an upturnedthreaded shank of a clamp block 5 see Fig. 3, and between the top of theclamp and the bottom of the guide a slotted lateral extension b securedto the auxiliary track I) is extended, the threaded shank of the clampblock extending through the slot in said extension and having at itsupper end a suitable clamping nut b By loosening the latter the pressureexerted by the clamp block upon the lateral extension 12 is relieved,and the auxiliary tracks 5 may be moved toward or from the guides K, andalso longitudinally along said guides by means of the slots b to adaptthem to blanks of various sizes. I

The side tracks Z) are secured rigidly to and laterally adjusted withthe paste pans H, lateral adjustment of the said pans being accomplishedby the slotted horizontal flanges h, see Figs. 5, 7, 7 and 15, securedto the ends of the pans and resting on suitable supports, to behereinafter described, and adjusting screws 6 are extended through theslots of the flanges and into the supports.

'An end gage or finger c is vertically movable in a suitable groovedhead 0 see Figs. 5 and 5 having laterally extended ears or flanges c,see dotted lines Fig.7, and full lines Fig. 5", at its upper end toenter guide-ways c in a bracket 0 see Figs. 5 and 7 secured to orforming a part of the head of the machine, to be described, clampingplates 0", see Fig. 5, secured to the under side of the bracket byadjusting bolts 0 and forming the bottoms of said guide-ways maintainingthe head 0' in horizontally adjusted position, according to the width ofthe blank tightening or loosening the said bolts 0 drawing the platestoward or removing them from the under sides of the flanges c of thehead 0'.

The end gage or finger c is engaged by the flanged base of an adjustingscrew 0 having its bearing in the head c',-rotation of the set screw inone or the other direction raising or lowering the gage or finger toaccommodate blanks of diiferent thicknesses, as in United States PatentNo. 98,976, dated June 6, 1893, so that but one blank can be movedforward under it at the same time, and, inasmuch as different blanks inthe pile of blanks will vary somewhat in thickness, the gage or fingeris vertically adjusted to permit the passage thereunder of thethickestblank that may be in the pile, and a yielding gage plate 0 is secured tothe-beveled lower end of the finger or end gage 0, see Fig. 5, the saidgage plate normally leaving sufficient space for the passage thereunderof a blank of average thickness.

' Should a thicker blank than the average be presented, its leading edgewill'engage the yielding gage plate e and will press the same upwardalong the beveled end of the gage or finger 0 against the pressure of aspring c' shown only in Fig. 5, until'it has been raised sufficiently topermit the passage thereunder of said blank, and after the latter hasbeen carried forward and positioned by the feeder, the yielding fingerwill move back into its normal position, preferably by a spring actingthereon, as in the patent referred to, but not herein shown. 7

It is important to maintain the blank perfectly fiat after it has beenfed forward beyond the end gage or finger c, and in order to accomplishthis, I have secured to the front of the grooved head 0 one part c of anadjustable presser foot, see Figs. 5, 5 and 5", shown as alongitudinally curved metallic plate, slotted at c at its end adjacentthe head, see Fig. 5, to embrace the end gage or finger c and permit themovement of the yielding gage plate 0 the curved plate being held inposition on the head 0 by set screws 7 ex- 'tended through slots in anear or lug 0 of the said plate, whereby the latter may be slightlyadjusted in a vertical direction according to the thickness of theblanks. The other part of the presser-foot is also shown as a curvedplate 0 cut away or slotted at and supported by an upturned arm 0thereon, which is connected to a carrier 0 see Figs. 5 and 5 adapted toslide and be maintained in adjusted position in a suitable clamp formedby two like depending cars 0 The inner side of one of said cars is shownin Fig. 5, the outer side of one of the ears being shown in Fig. 5", thegrooved head 0 and end gage or finger 0 having an opening therein toreceive the end of the carrier, as best shown in Fig. 5, the opening inthe end gage being clearly shown in Fig. 5. Suitable bolts 0 are passedthrough said ears, and the latter are drawn together thereby when thecarrier 0 is to be clamped. In the said Fig. 5, the two parts of thepresser are shown as pushed in, one upon the other, while in Figs. 5 and5 they are shown asdrawn out or extended in order to moreclearlyillustrate their construction and manner of adjustment.

The part 0 of the presseris moved toward or from the former to bedescribed according to the width of the blank to be fed, and it will beseen from the foregoing description. and an inspection of Figs. 1 and 5,that the longitudinal edges of the presser foot will bear upon the upperside of the blank on some-- what widely separated lines after it hasbeen fed forward beyond the end gage c, maintaining it perfectly flat asit is presented to the former and preventing buckling of the blank.

A spring stop 0 is secured to the under side of the plate 0 andextendedto the end thereof nearest the former, the saidstop rising topermit the passage of the blank as it is fed forward, but dropping backinto its normal position, shown in Fig. 5, behind the rear edge
